摘要

From the data recorded with the DELPHI detector at LEP in the years 1991–1992, 46497 events were selected having a high-momentum muon in hadron jets. A fit to the average electric charge sum of the jets recoiling against a b-quark jet tagged by a high-PT muon results in an average mixing parameter of View the MathML source.
